LAB 6. ACIDS AND BASES: PH AND BUFFERS PURPOSE: To determine the pH of common acids and bases using a pH meter‚ pH paper‚ and red cabbage indicator. To test the effect of adding an acid or base to a buffer solution. SAFETY CONCERNS: Always wear safety goggles. Wash with soap and water if skin contacts acids or bases. ACIDS: An Acid is a substance that when dissolved in water will produce hydrogen ions‚ H+‚ in the solution. An acid that does not contain carbon is called an inorganic

Ammonia and Hydrochloric Acid Lab Chemistry 1 Abstract The straw should be cut shorter to 8 cm in order to make the solid ring appear in the center of the straw. We achieved our goal‚ cutting the straw caused the gases to not have to go as far‚ and meet in the middle. Background The particles in a gas are very loose and tend to move around a lot very quickly. The particles in a solid are very compact and vibrate but don’t really move very much. The particles in a liquid however are more

cheese‚ tortilla chip‚ bread sticks‚ and gummy bears. Describing taste‚ flavor‚ appearance and texture was the task for this part. It was difficult to translate the flavors portion from ones tastebuds to paper‚ especially for tortilla chips. Trying to differentiate taste and flavor was also‚ again‚ difficult. In the text‚ on page 89‚ it states “taste relies on the sensation produced through the stimulation of the taste buds‚ while flavor is a broader concept.” For taste‚ the tortilla chip was salty‚ but

training‚ additional resources‚ and the use of consultants if necessary. Develop the project in modular form so users can test and approve the functional elements as you go along. Test every aspect of the site exhaustively. In this case we have Tony’s chips website already running‚ it is essential to gather the existing functional requirements. System analyst while gathering requirements can interview people from the old company‚ production support‚ gather system documentation and using FACT finding techniques

Suggested time allotment: 5 to 6 hours MODULE 2 ACIDS AND BASES In Module 1‚ you identified common properties of solutions using different methods. You learned how to report the amount of the components in a given volume of solution. You also found out that not all solutions are liquid. Some of them are solids and others are gases. Towards the end of the module‚ you investigated the factors that affect how fast a solid dissolves in water. Most of the solutions you studied in Module 1

has an effect o the rate of a chemical reaction. In chemistry we describe concentration in terms of the number of moles of a substance there are in every cubic decimetre (litre) of solution‚ written as moles.dm-3 of M for short. • In this experiment you will find out how increasing the concentration of the acid solution changes the rate of the reaction between dilute hydrochloric acid and magnesium metal. • As the metal reacts with the acid‚ hydrogen gas is produced and the metal dissolves

To produce dye based to the coupling of diazonium. 2. To understand the characteristic of dye orange II. INTRODUCTION The first dye was introduced by William Henry Perkin on 1856. It can be produced by the coupling of diazonium sulfanilic acid with nafthol in alkaline solution.. This was the common method used to produce dye nowadays. In this experiment‚ dye produced was the orange II. Azo compound is compound that contain azo group (-N=N-) between the conjugated aromatic ring and absorb
